, DUMPING-CAR.

Specification of Letters Patent.

Application filed February 1, 1916, Serial No. 75,526.

To 6621 whom it may concern.

Be it known that we, CHARLES H. .ANDRUS and CHARLES A. PLANE, citizens of the United States, and residents of Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented certain new and useful Improvements in Dumping-Cars; and we do hereby declare the following to be a full,

clear, and exact dcsgription of the inven tion such as will enable others skilled in the art to which it appertains. to make and use the same.

This invention relates to improvements in dumping cars and more particularly to doors for cars of the hopper type and operating means for such doors,one object being to so construct and arrange the doors or outlet gates as to avoid possibility of leakage of. material from the hopper body when said doors-are closed.

A further object is to so construct and" "of construction and combinations of .parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings; Figure 1 is a side elevation of a portion of a hopper car showing the application of our improvements; Fig. 2 is a,transverse sectional View, and Fig. 3 is a sectional view. onthe line 3-3 of Fig. 1.

1 represents the car body, and 2 the center girder: The body 1 is of the hopper type, having sloping end walls or floors 3, 3, and is divided centrally by a transverse hood 4 so that communicating hoppers 55 are formed at respective sides of the transverse center of the car. These hoppers are divided 'in their lower portions by means of hoods 6, 6, disposed over the center girder. At respective sides of the center girder, the 1nclined end floors 3 are extended to form the bottom walls of inclined chutes 6, the side Walls of each of which are made with curved free edges. Four inclined chutes 6 are thus provided, two at each side of the transverse center of the car and the chutes of the respective pairs being disposed to downwardly discharge toward each other and beneath the transverse hoodl.

Plates 7, 7, (having a generaltriangular shape) are securely riveted to respective sides of each chute and these plates may be connected by an integral plate member 8 lying against the bottom of the chutes,-the plates 7-8 thus forming a hood which partially incloses the chute.

The plates 7 are made with cur ed. free edges which conform to the curvature ofthe free edges of the side walls of the chute, and said free edges of the plates are made with laterally projecting-curved flanges 9. The

' upper portions of the plates 7 are offset, as at 10, to permit the attachment thereto of pivot bolts 11, and the sidewalls of the chute may be made with holes 12 to facilitate the securing of said' bolts. stitute' pivotal supports for brackets'12 to which doors or gates 13 are-secured. Each bracket 12 is curved at its free edge and provided with a curved flange 14. Each door or Nate 13 is made convex or curved outwardly to conform to the similar curvature of the free edges of the sides of the chute, and is secured at its respective ends to the curved flanges of two of the brackets 12. These brackets are made with grooves 14" which receive the flanges 9 of the plates 7 at respec- Pa-tented Dec. 5, 1916.

The bolts 11 contive sides of a discharge chute 6,-s0 as to prevent possibility of leakage of material past the edges of the door or gate when the same is closed, and also to form guiding means for the (1001' or gate when the same is being opened or closed. To further guard against leakage of material, each gate is provided at its lower edge witha flange 15 which, when I the gate is closed, engages the connectingplate 8 on the chute.

Brackets 16, depend car body and a bracket 17, depends from the center girdercentrally between the sides of the car. These brackets afford bearings for four transverse shafts, 18 and 22, located under the hood 4. Each shaft 18 is provided with two pairs of arms 19, the pairs of arms on one shaft 18 being connected by rods 20, with the doors or gates for the chutes at one side of the central hood 4'. and the pairs of arms 19 on the other shaft being similarly connected with the doors or gates of the chutes at the other side of said central hood. Each shaft-18 may be provided with a gear 21 to. receive motion'from, a pinion 23 on shaft 22, and a crank 2%, may be connected with each pina-Om the sides of the -j' ion or to each shaft 22 for operating the U same. Locking dogs 25 and 26 maybe prosed.

Our improvements afford simpie and effis ille/Iii? means for controlling the discharge of material from a hopper car; the doors or es are so curved outwardly as to operate ly against the pressure of the load, and construction is such as i: avoid possi city of leakage past the doors when the r is subje ted to jolting and vihrati transit.

23, The combination with a hopper body and an inclined chute depending therefrom, of plates secured to the sides of the chute, pivoted. to said plates and having conrex'free ends, said convex portions of the brackets having grooves, a convex gate secured to the convex portions of said bra ckcts, and curred flanges projecting from said plates and entering the grooves in the curved free ends 0 aid brackets.
